Los Angeles: Legendary pop musician Prince, who recently passed away at the age of 57, stayed awake for “154 hours straight (over six days)” despite being hooked on sleep-inducing painkillers, detectives have been told.

As the star’s family gathered at his home for a memorial 24 hours after his private cremation, his brother-in-law said that the singer had not slept for six and a half days before he was found dead in a lift, reports mirror.co.uk.
